1998 Dodge Caravan Outer Tie Rods

Don't know about cost. I would hope no more than $150 each (one on each side--they don't usually both wear out at the same time). If they're that loose, it could be a safety concern. Not too hard for a DIY-er to replace. Will still need shop to do wheel alignment afterward, though (which adds another $70 or so to the cost).

Heater tubes connect coolant passages of engine to heater hoses and heater. Not sure why they'd need immediate attention unless leaking or so rusty they look about to. Again, not something you want to just let go, given potential harm to engine if it overheats.
